This invention, relatesto looms and is more particularly directedto the lay assembly and its combination with the Vloom frame.

VIt is now the ordinary practice to assemble the weaving instrumentalities directly upon the loom lframe and for this purpose the loom parts are brought to the loom frame This is particularly so with respect to the lay and its attachments. In looms ofthe downwar-dlyV extending lay sword type it is now the usual practice to inount'the lower ends of the lay. swords upon a lrock shaft extending transversely of the loom and held in bearings in the loom frame sides.

L oomsare ordinarily grouped in large nurnbei's in,-l the weavingrooin, and in order to .econoinize space, theyare placed as close to gether asis. consistent with the` proper -operation'o the loomV parts. It becomes necessary at times to remove the lay rock shaft,

tora various reasons and in order to do this in the vweaving room, thev entire loom must be swungv out of position with its relation to other looms, in 1order that the long rock shaft may be w ithrdrawn.

One ofthe objects of the present inven- 'tion is toprovide alay assembly wherein the lay beam, the layswords, lshuttle boxes. andother attachments, such as the reed, for instance, may' be assembledas a unit at an assembly frame, and then as suoli unit -be readily applied tothe loom, and incidentalto such lay assembly 'as constitutes the presentinvention, the constructionfis so devised that the lay assembly as a unit may be readily reeration oflooms adjacent thereto or remov-l Y ing any of the looms-from place.

Other features of the invention and novel i 4combination of' parts will best be made clear Jfrom the following description and the vaccompanying drawings .of one good form of the invention;

inthe drawings, theloom frame andy otl erpartspassociatecfl .therewith are shown in dotted liines, while thei'eatuijes constituting` the present invention are indi-cated in. full lines, for the purpose of more. clearly eluci-l dating-the. present. invention.

the drawings, the loom frame iinay be,

station distant from the loom,`

of usual construction, .which ordinarily lcomprises a bottom tie bar or member 2 which extends` between theloom sides tokk i stands 7 secured one at eachfsidle 'of .the loom to the cross-tie 2.- In looms ofthe usual type, the lay rockshai't extends between the side frames'of the loom and on such rock shaft vthe lay swords are mounted, in order that thelay mayl Swine t@ and from the iront of thelooin .during the weaving operation,

and when the laylay swords and other parts jef the loom are assembled at the loom frame,

they partsfare placed individually in theirop'- erative relation directly Vupon theV loom ,n

fr-angle,`A ,Y In accordance with the present invention,

Vthe lay, lay. swords and other `lay attachments `are assembled at. an assembly station as aV unitand thereafter this. assembled unit is placeddirectly inthe looiri.v with the parts in their prolv'ierv relation@ y l As shown in thedrawings, the lay beam 8 may be of usual typeprovidedV with the o'r-y dinary shuttle Vracev 9, atV eachendof which the lay-vl beamV has mounted 'thereon the shutstle boXes10,'one at each side oliftheloo-in, I

and extendingl above the lay race is the reed ll held at4 its upper end inthe `rail 12, rlhese parts are., usuall assembled inoperative ielation at the loom trarne.,A

l In'the. lay.'assfeiiiblyy costitiiting the present invention, the lay beam .8Y has' secured thereto, as usual, the, lay swords 13 and 14, which extend downwardly from, the laybearn,` and i attheirilower ends yeacli of the' lay swords is provided with a studl shaft bearing. 1,5

which is preferably constituted as a sleeve or collar, as indicated inthe drawing,f f

The'. loornsides at theirlower portions arel each provided with main bearing `16. each of whichextends throughan opening in the loom sides in Vwhich it 4may be secufredby suitable means .such asv the,` bolts 17, and mounted'in. each of theY mainbearings 16I is a Studvsliettf 135 011e iifl Qffwhieliterrilirntese are secured at vtheir upper portions to the lay beam, be secured together' above the stud shaft bearings by a tie or cross-rod, which, in the present instance of the invention, is shown as the bar or rod 20, the end portions of which are received in sockets 21 projecting from the lay swords and provided with screw bolts 22, whereby the lay swords above the stud shaft bearing` 15 are tied together in their proper relation, an operation that may be performed at an assembly station remote fromthe loom frame, so that the lay, lay swords and attachments may be assembledvas a unit and then brought to the loom frame and assembled thereon f by the respective stud shafts 18.

Each of the stud shafts 18 extends from the inner side of the loom frame to the outer side thereof, and has mounted on its outer end portion a shoe 23 which may be detachably connected to the stud shaft by a suitable bolt 24C.V Each of the shoes 23 has its upper surface formed to receive the rocker 25 of the picker sticks 26.

Between the stud shaft bearing 15 at the lower end of each lay sword and the end of the bearing 16, a washer or collar 27 is in terposed, and the inner end portion of the rocker sleeve 28 bears upon the outer end of the main bearing 16, with thev result that when the stud shafts have secured thereto the studshaft bearings 15 and the sleeve 28, the 'stud shafts themselves will be held from endwise movement. y

Sincethe stud shafts 18 do not extend across theloom as is customary with the usual lay rock shaft, the lay assembly unit may be brought to the loom, each of the studv shafts 18 be placed in operative position with the stud shaft bearings A15 .secured thereto at the inner end of each stud shaft,V

and the shoe 23 securedto the outer end portion of the stud shafts. Should it become 24; of the shoe, to enable each stud .shaft to j be Withdrawn, without at the same time Y disturbing the position of the loom in the weaving` room. Y.

Y By the construction described, which embodies the presentinvention, the lay and its prevent attachments may be assembled as a. unit at a distant station and then brought to the loom frame as such unit and applied to the loom as hereinbefore described, and similarly,

should it be necessary at any time to renew .the bearings or other parts or to remove the lay assembly, it is only necessary to ,withdraw the short stud shafts without disturbing the position of the loom with its relation to other looms vin the weaving` room.

The tie or rod 20 which constitutes part of the lay assembly is preferably secured to the lay swords near the lower end portionsl thereof above the stud shaft bearings 15, so that the entire lay assembly is rigidly held in proper position for applicationV to or removal fro-m the loom.

`What is claimed is:

1. ln a loom, the combination of the loom side frames, shaft bearings at the lower porn tion thereof, a stud shaft mounted in each bearing,l and terminating on the inside of each side frame, a lay assembly comprising the lay beam and lay swords each having a stud shaft bearing` at its lower portion, a

tie rod extendingv between and secured to the lay swordsabove the stud shaft bearing to prevent relative movement ofthe lay Y side frames, shaft bearings at vthe lower por tion thereof, a stud shaft mounted ineach bearing and terminating' at the inside of each side frame, a lay assembly comprising the lay beam and vlay swords each having` a stud shaft bearing at its .lower portion, a tie rod extending' between and secured to thel lay swords above the stud shaft bearing `to relative movement:v of the lay swords, a picker stick` rocker vdetachably se.-V cured to the outer portion of each stud shaft and means for detachably securing;` the stud shaft bearings to thc stud shafts to permit withdrawal of the stud shafts from the stud shaft bearings that the lay assembly may be readily removed from or applied to the loom as a'- unit while the loom remains in normalk weaving position. y Y

3. ln a loom, the combination of the loom` frame having shaft bearings at its lower portion, a separated studA shaft mounted in each bearing, and a layV assembly comprising the lay beam having lay swords secured thereto, a stud shaft bearing at the lower portion of each lay sword, a tie rod ex'- tending between and secured to the lay swords above the lay sword bearings, and means for detachably securing each of thelay sword bearings to the adjacent stud shaft that the latter maybe removed from the bearings to permit the lay assembly to be readily removed from or placed in the loom as a unit. y

rod extending between and secured to the lay swords abovethe stud' shaft bearings, means for detachably connecting` each of the stud shaft bearings to its stud shaft inside the loom frame that the stud shafts may be readily removed from the stud shaft bearings and the lay assembly from the loom as a unit. i y

5. in a loom, a lay assembly comprising the lay beam having a shuttle race and shuttle boxes, downwardly extending lay swords secured to the lay beam and having bearings at their lower portions, a tiemember extending' between and secured to the lay swords above thebearings and holding the parts in assembled relation and a separate supporting rocker stud shaft for each of the lay sword bearingsvthat the lay and its attachments may be assembled as a unit and readily' applied to or removed from the loom. Y

In a loom, the combination of a lay assembly unit comprising the lay Abeam and shuttle boxes, lay swords secured at their upper ends to theplay beam and having bearings at their lower ends, a tie rod eX- tending between and secured to the lay swords above the bearings, and separate stud shaft mounted one at each side of the loom and extending into the adjacent lay sword bearing that the lay and attachments may be assembled as a unit and as suoli ybe applied to or removed from the loom.

In testimony whereof, I have signed my name to' this speciticatio HARRY A. DAVIS.
